Replacement for Antec PP-303X SP-350

This 300W ATX power supply replaces the Antec PP-303X SP-350 unit. It fits standard ATX cases and delivers steady power for desktop repairs or upgrades. The grey enclosure houses a single fan for cooling.

300W continuous output

The supply provides 300 watts of continuous power. That single figure determines whether it can run your components without shutting down. Check your system draw against this rating before buying.

Three SATA and legacy connectors

The unit includes three SATA power connectors, two peripheral connectors, one floppy connector, a 20+4-pin ATX connector and a 4-pin ATX12V connector. It handles older drives and basic motherboards comfortably; it runs out when a build needs PCIe power cables or more than three SATA devices.

商品問答

What does the 300W rating mean for a desktop build?

The 300W rating indicates the maximum continuous power this unit can deliver to components like the CPU, graphics card, and drives. It suits basic office PCs or older systems with modest power draw.

How does the ATX form factor limit compatibility?

The ATX form factor sets the physical dimensions and mounting hole pattern. It fits standard ATX cases but will not fit slimline, SFX, or proprietary chassis that require a different size.

What clearance is needed for the single fan and connector layout?

The unit uses one fan for exhaust, so the case must allow airflow at the rear. The 20+4-pin ATX, 4-pin ATX12V, two peripheral, one floppy, and three SATA connectors require enough cable routing space behind the motherboard tray.
